Key Excavator Hammer Parts and Their Functions

Housing

The housing serves as the protective shell for your excavator hammer. It shields the internal components from external damage caused by debris, dust, or accidental impacts. This robust casing ensures the hammer remains functional even in harsh environments. Its durability allows you to operate the equipment in challenging conditions without worrying about frequent repairs or replacements.

Piston

The piston is the powerhouse of your excavator hammer. It converts hydraulic energy into mechanical force, enabling the hammering action that breaks through tough materials. Here’s how it works:

• Hydraulic breakers rely on hydraulic principles, where pressure applied to a fluid transmits force throughout the system.

• Oil flows into the hammer via a valve, building pressure in the upper chamber during the upward stroke.

• When the lower chamber releases pressure, the piston moves upward. The upper chamber then becomes high-pressure, driving the piston downward to deliver powerful blows.

This process ensures consistent and efficient performance, making the piston a critical component of your excavator hammer parts.

Tool (Chisel or Moil Point)

The tool, often a chisel or moil point, is the working end of the hammer. It directly impacts the material, breaking it apart. The choice between a chisel and a moil point depends on the task at hand:

Selecting the right tool shape is essential for effective operation. A pointed tool works best for hard surfaces, while a flat tool is ideal for breaking up concrete. By choosing the appropriate tool, you can maximize the hammer’s efficiency and minimize wear.

The nitrogen chamber plays a crucial role in your excavator hammer’s performance. It stores compressed nitrogen gas, which acts as a secondary power source. This gas amplifies the force generated by the hydraulic system, ensuring each hammer strike delivers maximum impact. Without the nitrogen chamber, the hammer would rely solely on hydraulic pressure, reducing its overall efficiency.

Another important function of the nitrogen chamber is shock absorption. When the hammer strikes a hard surface, the impact generates significant vibrations. These vibrations can damage internal components over time. The nitrogen gas cushions these shocks, protecting the hammer’s internal parts and extending its lifespan.

Note: Always check the nitrogen pressure regularly. Low pressure can reduce the hammer’s power and increase wear on other components.

Enhances the hammer’s efficiency and performance

A well-maintained nitrogen chamber ensures your excavator hammer operates at peak efficiency. By providing additional power, it reduces the workload on the hydraulic system. This not only improves the hammer’s performance but also minimizes fuel consumption, saving you money in the long run.

The nitrogen chamber also contributes to consistent hammering action. It maintains steady pressure levels, ensuring each strike is as powerful as the last. This consistency is especially important when working on tough materials like reinforced concrete or rock.

• Key Benefits of the Nitrogen Chamber:

  • Increases hammering force for better material breaking.

  • Reduces wear and tear on hydraulic components.

  • Improves fuel efficiency by optimizing power usage.

Tip: Use a pressure gauge to monitor the nitrogen chamber. Maintaining the correct pressure level is essential for optimal performance.

By understanding the nitrogen chamber’s role, you can ensure your excavator hammer remains efficient and reliable during demanding tasks.
